我们展示了一种相敏升压技术，用于扩展112 Gb/s DP-QPSK的范围。我们沿着相位共轭闲频传输信号。通过联合检测它们并利用相位共轭对它们求和，部分地减轻了非线性。
We demonstrate a phase-sensitive boosting technique for extending the reach of 112-Gb/s DP-QPSK. We transmit the signal alongside a phase-conjugated idler. Nonlinearity is partially mitigated by detecting them jointly and summing them with phase conjugation.
